The existing rate limiter was moved to a separate package and renamed to IntervalLimiter. Added BurstLimiter which is a wrapper around the "golang.org/x/time/rate" package. The conf.Rate type now has a private `typ` field that indicates if it is a "interval" or "burst" rate limiter. If the config value is in the form of "<burst>/<rate>" we set it to "burst", otherwise "interval". The conf.Rate.GetRateType() method is then called from the ratelimit.New package to determine the underlying type of `ratelimit.Limiter` returned from `ratelimit.New`. Finally we changed `api.NewLimiterOptions` to call `ratelimit.New` instead of creating a specific type of rate limiter.

We have a special case check for rate limits of 0 in some areas of the code. Eventually I would like to remove those so I'm going to set the rate limit of 0 as a valid rate limit which allows no events.

The existing rate limiter was moved to a separate package and renamed to IntervalLimiter. Added BurstLimiter which is a wrapper around the "golang.org/x/time/rate" package. The conf.Rate type now has a private `typ` field that indicates if it is a `"interval"` or `"burst"` rate limiter. If the config value is in the form of `"<burst>/<rate>"` we set it to `"burst"`, otherwise `"interval"`. The `conf.Rate.GetRateType()` method is then called from the `ratelimit.New` function to determine the underlying type of `ratelimit.Limiter` it returns. Then changed `api.NewLimiterOptions` to call `ratelimit.New` instead of creating a specific type of rate limiter. --------- Co-authored-by: Chris Stockton <[email protected]>
